Increasingly Elevated Liver Enzymes

Reasonably healthy overweight inactive 58 year old F with long term IBS Allergies GERD and ankle arthritis. I  have never used drugs or alcohol. I take Tylenol, Zantac 150 and Zyretc D and 4 Way Nasal spray conservatively every day. In January after a fall in which I struck my abdomen and broke a rib with muscle strains my ALT level was 131, AST 88 and ALP 458. Retested 6 mos later now enzymes increased ALT 254, AST 199 and ALP 199. Abdominal ultrasound showed 1.3 cm gallstone and several small stones but no signs of inflammation, cirrhosis, liver heterogeneous, no masses or obstructions, everything else normal. I do have fatigue, poor sleep and itching. X rays of left ankle show severe arthritic deterioration. Recent food born illness and influenza over the last 6 weeks. Could these have caused the elevation? Can gallstones cause that much of an increase? Could it be related to the arthritis?
